Android - Wizard with multiple fragments - Back button behavior -


imagine have mainactivity shows list of tasks. can add new task list clicking standard fab button. after new wizardactivity starts. adding new task 3 step process (each step single fragment):

enter image description here

i need advice button behavior arrow in toolbar.

let's i'm in step 2, should on pressed? move step 1 or close activity? what's best ux pattern here? maybe should remove additional back , next buttons , move them toolbar (kinda on ios)? want right, intuitive.

you can consider use button of device navigate step 3->step2->step1.

if in step1 close activity.

also don't forget save instance of fragment in step1 , step2 when user go previous fragment edit he/she not have give data again.

instead of using external back/next button put next button each of fragment , let user choose go previous fragment using tab or pressing hardware button.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
